Takes quite a long time indeed and is prevalent in some areas more than others. Some people may never be cured if it hooks to an area like the ventricles you can't perform surgery there to remove it and it doesn't respond to drugs. Can cause anything from blindness to coma to death depending on where they lodge. A3ooth billah!
